I don't know for sure that this piece is Mexican (haven't seen it witha label), but the quality and color of the glass reminds me a lot of other Mexican glass I see here in LA. There are many vendors at the flea markets here who offer booths full of Mexican glass - the little roosters that are all over ebay (sold as Murano), and weird vases that look like they were held upside down so that all the glass ran to the top.

Look at ebay item 7367528883 for a Mexican glass owl. Compare the look of the glass to the bowl.
